Chemical Composition of D2 Tool Steel
D2 is a high-carbon, high-chromium cold work tool steel. Its high carbide volume is the reason it delivers strong abrasion resistance in demanding tooling environments.
| Element | Content (%) |
|---|---|
| C | 1.40 – 1.60 |
| Cr | 11.0 – 13.0 |
| Mo | 0.70 – 1.20 |
| V | 0.50 – 1.10 |
Typical Applications
D2 round bar is commonly selected for tooling where abrasive wear is the dominant failure mode and impact load is relatively controlled.
- Blanking dies
- Punches and die inserts
- Shear blades
- Thread rolling dies
- Cold forming tools
- Slitting knives
- Industrial wear parts
